In our example for blade grinding we us TOA or Tangent for Opposite divide by Adjacent. Let's put some real numbers in. Say our knife is going to be a hefty 0.25" thick. We take 1/2 of that to make the right triangle, so O is 0.125". We'd like a grind height of 3/4" or 0.75".

Feeds and Speeds Charts - ShopBot Tools

50%. If doing this, it will be necessary to calculate the feed rate and speed instead of using the chart. Example using a 1/4” or 0.125” bit – Straight V Carbide Tipped Endmill SB# 13642: This bit is used for soft wood, at a depth of 1/2” (two times the diameter). The chart cannot be used for this calculation.
